A collector originally purchased an autographed football for $450. After holding onto the football for a number of years, the collector decides to sell the item on eBay at a markup of 80%. What price is the
collector charging for the football?

810

Step-by-step explanation:

450 × 1.80 = 810

The 1 represents how there is no markdown and the .80 is the 80% being marked up.

I think there is a more specific equation for this than the one I showed, but this was my way of solving these questions without giving myself a headache

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
